Ten previously undescribed lanostane-type triterpenoids (1–10), together with 15 known lanostanes, were isolated from artificially cultivated fruiting bodies of the basidiomycete Ganoderma sp. BCC 21329. The structures were elucidated on the basis of NMR spectroscopic and mass spectrometry data and by application of the modified Mosher’s method. Compounds 1, 3, 5, and 7 showed moderate antimalarial activity (IC₅₀ 3.8–7.6 μg ml⁻¹).
